RADIATOR.

Application filed March 26, 1921.

To all whom it may concern:

Be it known that 1, PAUL A. STURTEVANT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Radiators, of which the following is a specification.

This invention relates to radiators for motor vehicles and consists in the matters hereinafter described and more particularly pointed out in the appended claims.

In the accompanying drawings- Fig. 1 is a front view of a radiator constructed in accordance with my invention;

Fig. 2 is an enlarged vertical sectional view taken on line 2-2 of Fig. 1;

Fig. 3 is a cross-sectional view of one of the water tubes of the core;

Fig. 4 is an enlarged fragmentary view taken on line 4-4 of F 1; and

Fig. 5 is a front view of a radiator of my invention with a circular outer casing instead of a rectangular one as shown in Fig. 1.

The radiator shown in Figs. 1 and 2, coinprises an outer casing 1 rectangular in form and made in tWo separable sections 2 and 23 secured together at the sides of the radiator by bolts 1- extending through webs provided there for that purpose. The sections 2 and 3 are arranged one above the other, and each is made of cast metal and has its inner side semicircular in shape and open, as illustrated in the drawings. The top section 2 has a filling neck 5 normally closed. by a cap 6. This section also has at its rear an inlet opening 7, and the bottom section 3 has an outlet opening 8, as usual in radiator construction.

In the outer casing 1 is a core, which, as shown, comprises a centrally arranged drum 9, concentric with the circle formed by the circular inside edges of the sections 2 and 3 when clamped together. From this center drum 9 radiate water tubes 10, which have their outer ends extended through and soldered or otherwise tightly secured to an annular head sheet 11. This is in the form of a continuous and unbroken band, made of copper and designed to fit against the circular edges of the sections 2, 3 and close the inner side thereof, as shown in Figs. 2 and 4.

The core, as shown and described, is radial, and to clamp or secure it in place in the casing 1, I provide the following con struction. Each section 2, 3 has along each circular inner edge an outwardly projecting Serial No. 455,963.

flange 12. The head sheet 11 overlaps these flanges 12, 12 and is held against them by two one-piece, solid rings 13, 13, as shown in Fig. 4:. The head sheet being of copper serves as a gasket between the sections 2 and 3 and the rings 13, and the latter have annular grooves 1 1 to receive annular beads 15 on the flanges 12 to hold the head sheetbetween such parts. When the bolts 4: are tightened to clamp the sections together, the rings 13 are also clamped to hold the core in the outer casing 1.

To remove the core for cleaning or repair,

all that need be done is to remove the bolts 4-, remove the rings 13, and take off the top section 2. This releases the core, and the same may then be bodily removed out of the bottom section To replace the core, the same is put back on the bottom section, the rings positioned, the top section replaced, and all clamped together by the bolts 4, as is obvious. The drum 9, as shown, has front and rear walls or plates 16 and 17 both secured to the interposed tubular wall of the drum by crimp seams, as shown in Fig. 2. The inner ends of the tubes 10 extend through and are secured to this wall. To permit access to be had into the drums for the purpose of cleaning or repair, the front *all 16 is provided with a hand hole 18. This is closed by a cover plate 19. The hole and cover plate are oval in shape to permit the latter to be inserted into and removed from the drum by passing the cover edgewise through said hole. The cover plate, when in closed position, is inside of the drum, and is held closed by a screw 20 extending through a. tripod 21 on the outside of the d rum. The legs of the tripod bear on a cast ring 22 secured to the front wall 16 about the hole or opening 18, and are held against the same to hold the cover plate tightly against the drum wall 16 by a clamp nut 23.

As shown in the drawings, the water tubes 10 are elongated tansversely, and are preferably as wide as the drum between the seams of the front and rear walls. In the radiator illustrated, the front and rear edges of the tubes are vertically straight.

The outer casing 1 of the radiator shown in Fig. 1 is rectangular, and the upper section 2 has a plurality of heat radiating fins or flanges 24:. In Fig. 5, the outer casing of the radiator there shown is circular in shape, and has two sections 25, 26 clamped about a core by bolts 27 as before. The upper section of this circular radiator also has heat radiating fins or flanges 28. The core and the remainder of the construction is the same as previously described.

The lower section of each radiator shown in Figs. 1 and 5 may be provided with side lugs (not shown) to enable the-radiator to be bolted or otherwise secured to the chassis or frame of the motor vehicle.

I claim as my invention:

1. A radiator for motor vehicles, comprising a core, a hollow outer casing surrounding said core and divided into separable sections open along the inside thereof, said core having water circulating tubes and a head sheet surrounding the core, said head sheet extending across and closing the opening along the inside of said sections, said tubes secured to said head sheet and opening into said outer casing through the head sheet, means for holding the marginal portions of said head sheet against said sections on opposite sides of the opening therein, and means for releasably clamping said sections together about said core.

2. A radiator for motor vehicles, comprising a core, a hollow outer casing surrounding said core and divided into two separable sections arranged one above the other with their meeting edges on opposite sides of the core, each section having its inside face substantially semicircular in form and open along the length thereof, said core hav ing radially arranged water circulating tubes communicating with each other at their inner ends adjacent the center of the core, an annular head sheet surrounding and extending across and closing the opening in the inner face of each of said sections, said tubes secured to said head sheet at their outer ends and opening into said sections through the head sheet, rings for holding the marginal portions of said head sheet against the sections on opposite sides of the openings therein, and means for releasably clamping the sections together about said core.

3. A radiator for motor vehicles, comprising a core, a hollow outer casing surrounding said core and divided into two separable sections arranged one above the other with their meeting edges on opposite sides of the core, each section having its inside face substantially semicircular in form and open along the length thereof, said core having radially arranged water circulating tubes communicating with each other at their inner ends adjacent the center of the core, an annular head sheet surrounding and extending across and. closing the opening in the inner face of each of said sections, said tubes secured to said head sheet at their outer ends and opening into said sections through the head sheet, rings for holding the marginal portions of said head sheet against the sections on opposite sides of the openings therein, said sections having integral beads to enter annular grooves in said rings, and means for releasably clamping the sections together about said core.

4. A radiator for motor vehicles, comprising a core, a hollow outer casing surrounding said eore and divided into two separable sections arranged one above the other with their meeting edges on opposite sides of the core, each section having its inside face substantially semicircular in form and open along the length thereof, said core having a tubular drum at the center thereof, water circulating tubes radiating outward from said drum and having their inner ends secured to the drum and opening into the same, an annular head sheet surrounding and extending-across and closing the open ing in the inner face of each of said sections, said tubes secured to said head sheet at their outer ends and opening into said sections through the head sheet, rings for holding the marginal portions of said head sheet against the sections on opposite sides of the openings therein, and means for releasahly clamping the sections together about said core. I

5. A radiator for motor vehicles, comprising a core, a hollow outer casing surrounding said core, said core having a tubular drum at the center thereof, said drum having a rear wall and a front wall, the latter having a hand hole therein, a cover plate placed in said drum for closing said hand hole, means outside of said drum and engaging said cover plate through said hand hole for clamping said cover plate over said hand hole, and water circulating tubes radiating outward from said drum, said tubes having their inner ends secured to and opening into said drum and their outer ends opening into said outer casing.

In testimony that I claim the foregoing as my invention, I affix my signature, this 8th day of March, A. D. 1921.

PAUL A. STURTEVANT.
